'To all whom itfmay concern:

Be it known that I, Gnoncn H. Moons, of

Boston, in the county of Suffolk and State of a Massachusetts, have invented certain. new and useful, I'm rovements in Temporary Binders, of wln'c the following is a specification.

This invention relatesto devices for temporarily holding loose sheets in a cover composed of side pieces and a back to which the side pieces are flexibly connected, the leaves heing-detachably secured to the back so that gheyl; can be manipulated like the pages of a The invention relates particularly to that shaft is journaled' in bearings on the back or connecting portion of the cover, and is provided at its ends with hooksadapted topass through orifices formed for their reception in the leaves or sheets, the back being provided with catches to engage said hooks, and hold them in position'to secure the leaves.

The invention has for its object to providea simpleand ellicient device of this character, inwhich the rock shaft, the catches which engage its hooks, and the sockets and bearings in which the rock shaft is journaled, are

cover after the latter has been coin leted, so that no operations incidental to t e manufracture of the cover are re uired to hold the rock shaft and catches in p ace.

Otherwise stated, the object of the invenof time and labor involved in'manufacturing ferred to, and to produce a device of the utmost simplicity, strength and durability.

The invention consists in the improvements which I will now proceed to describe Of the accompanying drawings, forming a part of this spcci'l'ication,l igure 1 represents a'perspective view of a tem orary binder embodying my invention. l ig. 2

from the cover. ig. 4 represents a view similar to Fig. 3, showing a portion of the rock shaft and one of its hooks engaged with Fig. 5 represents a section on referredto, made in two parts or sections. The same letters of reference indicate the same arts in all the figures.

In the drawings 12 12 represent thelids or spective view showingthe plate hereinafter sides, and 1'3 re resents the connecting ortion or back wit which the sides 12'are exibly connected in the usual or any suitable manner, the parts 12 12 and11'3 constitutinga cover such as is ordinarily made by processes and methods commonly practiced by book binders.

Upon the inner side 'of' the back 13 is laced a sheet metal plate, comprising a fla't hody portion 14 and lon itudi'nally extending bosses or beads 15 16 ormed by embossing the edge portions of the late, thesaid beads presenting semi-cylin rical external surfaces which project from the back 13.

The outer edges of. the bosses are substantially flush with the inner side of the body portion 14of' the plate, so that they hear collectively formin longitudinal sockets. The socket formed by the boss 15 receives the rock shaft 17, on the end portions of which are formed the hooks 18 which are adapted to engage perforations formed in loose sheets. The hooks 18 are, formed to extend across the plate, and enter orifices 19 formed for their reception in the boss 16. One side of each hook is rovided' with a notch which forms a shou der 20 (Fig. 5) adapted to engage the ortion of the boss 16 which forms one end 0 an orifice 19, the arrangement being such that when the outer end ofthe hook 18 is swung downwardly into the opening 19, the shoulder 20 will engage one end of the orifice, as shown in Fig. 5, the engaged end of the orifice constituting a catch, and the shoulder 20 of the hook snapping or springing into engagement with said catch by the resilience of the hook. The bod portion 14 of the plate is united to the bacr 13 by fastening devices, which are preferably eyelets 31. the setting flanges of the eyelets being preferably arranged to bear upon the outer surface of theback 13, while the spread or upset ends of the eyelet tubes are upon the'outer-surface of the body portion 14 of the plate.

From the foregoing it will be seen that when the hooks 18 are swung over toward the boss 16, their shoulders 20 will s rii'lg into engagement with the portions 0' the line 5-5 of Fig. 4. Fig. 6 represents a perboss 16 which form the ends of the orifices against the back 13, the bosses and. the back 19, the hooks being thus securely held in their leaf-securing position. When it is de-' sired to remove the leaves, the hooks may be sprung out of engagement with their catches and swung outwar ly from the boss 16.

My invention is characterized chiefly; by the sheet metal plate having the body portion 14 adapted to bear upon the inner side of the back 13, and to be secured thereto by eyelets or other equivalent fastenings,'and by the bosses 15 16 formed at opposite edges of the body portion of -the plate. Said bosses not only provide a bearing for the rock shaft, and catches for the hooks, but they furthermore strengthen and stiffen the sheet metal plate so that it is not liable to be bent crosswise. The body portion 14 of the plate being recessed or offset below the highest portions of the bosses, is enabled to have a fiat and extended bearing on the inner surface of the back, and to be secured thereto by fastening devices which are independent of the structure of the back. Hence the sheets or layers of which the sides 12 and back 13 are formed, are adapted to be assembled, cemented together and dried, while held fiat and under ressure, to form a complete cover before t e operation of connectmg the rock shaft and catches to the back. Heretofore it has been necessary to utilize parts of the material of the back in securing the bearings and catches of the rock shaft to the back, an operation which involves a reat deal more expenditure of time and l abor, and therefore entails more expense than is required in the production of my improved binder I here shown, which is produced by sim ly securing to a cover that has been previous y formed in a complete condition, the sheet metal plate having the bosses and the rock shaft engaged with one of the bosses. The hook s 18 have beveled outer ends 22 which bear upon the crown of the arched rib 16 in close proximity to the apertures 1.9 when the hooks are moved toward their locking position. The beveled ends 22 cause the deflection of the hooks into the apertures 19 when said ends are pressed against the rib 16. The arched form'of the rib enables it to resist the pressure of the ends of the hooks against it without yielding or bending inwardl The plate may be made in .two indepen ent parts or sections, each having one of the apertures 19, as shown, in Fig. 6, without departing from the spirit of my; invention.

. claim:

1. A device. of the character stated comprising a back, a sheet metal late having an mtgrmediate portion secure to said back an whic is formed with catches, and a rock shaft journaled beneath the other rib and having shouldered hooks to engage said catches, the inner sides of said ribs being integ'ral with and rising directly from the intermediate portion which is secured to the back.

2. A temporary binder comprising a cover having side pieces and a connecting back portion, a sheet metal plate su orted upon the inner side of the back, anrflbngitudinal 1provided with longitudinal ribs one of semi-cylindrical ribs offset from the body portion, and located at opppsite edges thereof to form longitudinal soc ets, a rock shaft journaled in one of said sockets, and having shouldered hooks, the other rib having catches and forming arched hook-engaging members, and'fastem'ng devices securing the body portion ofthe plate to the back.

. 3. temporary binder comprising a cover having side pieces and a connecting back Eortion, a sheet metal plate composed of a at body portion bearing upon the inner side of the back, and longitudinal semi-cylindrical arched'ribs offset from the body portion and located at opposite edges thereof, one of said ribs having apertures in its crown portion, a rock shaft ournaIed in the other rib and having shouldered hooks provided with beveled outer ends, each adapted to bear upon and be deflected by the crown of the apertured rib into one of said orifices, the arched form ofthe rib the pressure of the hook.

'In testimony whereof I have aflixed my signature, in presence of two witnesses.
